Abstract: A more energy-efficient method of processing crude oil is achieved by viscoelastic shearing in order to increase the vapor pressure of the crude oil. This change in vapor pressure allows a more efficient separation of volatile components from non-volatile components in the crude oil. By optimizing the energy expenditure for shearing and the energy expenditure for separating the volatile components from the non-volatile components of the crude oil, while simultaneously removing the volatile components by distillation, one can reduce the overall energy input for the separation. Alternatively, it is possible to affect the distillation at a reduced temperature.

Abstract: Improved crude oil processing is achieved by viscoelastic shearing of crude oil at an elevated temperature. The shearing provides for an enriched light fraction and an enriched heavy fraction that can be more efficiently separated by distillation. Shearing is achieved using a mobile surface and immobile surface, or other flow geometry, under conditions providing for a transient phase separation.

Abstract: Articles having porous or foam-like elements are provided. The design, fabrication and structures of the articles exploit properties of reactive composite materials (RCM) and their reaction products. In particular, fluids generated by reacting RCM are utilized to create or fill voids in the porous or foam-like elements.

Abstract: The present invention relates to the separation, quantitative measurement, and analysis of trace species using a combination of three steps in succession. First, trace species are separated from other species that are present. Second, the trace species are chemically modified to convert them into specific species that are advantageous for the third and final step. In this last step, cavity enhanced optical detection of the converted species is performed to detect and measure the concentrations of the species of interest. Because the last step has spectroscopic resolution, the concentration of isotopologues in each converted species can be determined. Further processing can provide the ratios between pairs of isotopologues, in particular the ratio of the rare isotopologues to the most abundant isotopologue.

Abstract: By connecting the Bradbury-Nielson gate (BNG) directly to a driver without a transmission line, distortion of the voltage waveform experienced a the BNG are much reduced. Because the magnitude of the modulation defects grows as the applied modulation voltage is increased, Bradbury-Nielson gates with finer wire spacing such as 100 microns, and operating at 10 to 15 V, significantly better signal-to-noise ratios are achieved. HT-TOFMS data were also post processed using an exact knowledge of the modulation defects.

Abstract: A Bradbury-Nielson gate (BNG) includes a set of evenly spaced, co-planar, and parallel wires. The wires alternate in a repeating ABAB pattern, where all of the A wires are electrically connected to each other, all of the B wires are electrically connected to each other, and the set of A wires is electrically isolated from the set of B wires. Improved fabrication of Bradbury-Nielson gates is provided based on two key ideas. The first key idea is the use of wire positioning template surfaces having wire insertion features with enhanced spacing. Wire insertion features having enhanced spacing allow for non-microscopic assembly of finely spaced wire arrays. The second key idea is the use of two template surfaces, each having wires spaced by twice the eventual gate wire spacing. The use of two template surfaces facilitates making the alternating electrical contact required for a BNG.

Abstract: The present invention provides a method of coating an electrospray emitter with silver and then gold utilizing wet-coating processes. First, the electrospray emitter is immersed in a silver-containing liquid solution to coat the electrospray emitter in a layer of silver. Next, the silver-coated electrospray emitter is removed from the silver solution and rinsed with water. The silver-coated electrospray emitter is then annealed to stabilize the silver layer. Once the silver layer has been stabilized, the silver-coated electrospray emitter is immersed into a gold-containing liquid solution and a voltage is applied. This voltage serves to electrochemically deposit a gold layer onto the silver layer. The gold- and silver-coated electrospray emitter is then removed from the gold-containing liquid solution and rinsed with water and, preferably, with nitric acid.
